A series of experiments have been carried out to study on the efficiencies in solar energy materials and solar cells. Dye-sensitized solar cells (DSSCs) are good examples of where the quality of the nanomaterials and their interfacial properties are important to device performance. In this report, Nanometer TiO2sol for coating film was prepared by cooperating hydrothermal colloidal sol with organic polymer dispersing agent (PVA). Nanocrystalline TiO2porous films were prepared by using electro-hydrodynamic technique (EHD). The results show the films prepared by EHD technique have multilevel hierarchical structure, therefore, better optical scattering properties. Different constituent quasi-solid electrolytes with blood mimetic thixotropy were prepared by cooperating ionic liquid electrolyte with nanometer TiO2colloidal sol synthetized by sol-gel method. The resulting Quasi-Solid-State dye-sensitized solar cells consist of nanoporous TiO2Film and the dye N3, show conversion efficiencies up to 3.7 percent (8. 51 percent with a mask). |
